Embodiment 1
[0054] Such as Figure 1a As shown, the delivery system of the heart assist device provided by the present invention (hereinafter referred to as "the delivery system") includes a retractable assembly 10 and a traction assembly 20, and the retractable assembly 10 includes a retractable handle 101, which is located far from the retractable handle 101 The retractable strip assembly 100 at the end and the retractable connecting piece 102 for fixedly connecting the retractable handle 101 and the retractable strip assembly 100, the retractable strip assembly 100 is composed of multiple Arranged and composed of retractable strips 1000 divergent to the far end, the proximal end of the retractable strip assembly 100 is fixedly connected with the retractable connector 102; The traction handle 201, the retractable strip assembly 100 is connected with the traction connector 200, the traction handle 201 or the retractable handle 101 is operated, and the relative position of the two is chang...
Embodiment 2
[0063] Such as Figure 6 to Figure 11 As shown, based on the first embodiment, the difference between the second embodiment and the first embodiment is that the traction connector 200 includes a traction platen 202 arranged in the space surrounded by a plurality of retractable strips 1000, and the traction platen 202 is coaxial with the retractable connector 102, the traction pressure plate 202 is connected with the traction handle 201 through the traction connector 200, in this case, the traction pressure of the retractable strip assembly 100 and the traction connector 200 Disk 202 is connected. In one embodiment, the traction connector 200 is multiple traction wires 2000 , one end of the multiple traction wires 2000 is connected to the traction platen 202 , and the other end of the multiple traction wires 2000 is connected to the traction handle 201 . In one embodiment, the traction connector 200 is composed of one or more traction wires 2000 and a traction connection trans...
Embodiment 3
[0069] Such as Figure 12 As shown, based on the first embodiment, the first difference between the third embodiment and the first embodiment is that the delivery system also includes an implant release assembly, which consists of an implant release handle 301 and an implant release handle 301. The implant release wire 3000 is composed of an implant release handle 301 that can slide relative to the traction connector 200 or the retractable connector 102. There are one or more implant release wires 3000; in heart assist devices (that is: implant) in the unreleased state, the distal end of the implant release wire 3000 fits with the distal end of the retractable strip 1000, and further, in order to make the two fit better, the retractable The outside of the strip 1000 and the implant release wire 3000 cover the retractable strip sleeve 1001 at least in their distal regions. In addition, if Figure 1b and Figure 14 As shown, in one embodiment, the retractable bar 1000 can be ...
